WILLIAM PoLATsIK', OF oH oAeo, ILLINOIS, ASSIGNOR TO HIMSELF AND JOSEPH L. BLOOM, PROCESS FOR PRODUCING WHALEBQNE e RUBBER SUBSTITUTESr To all whom it may concern.-

Be it known that 1, WILLIAM POLATSIK, a subject of the Emperor of Austria-Hungary, residing at Chicago, in the county of Cook and State bf Illinois, have invented certain new and useful Im rovements in Processes tutes; and I do hereby declare the following to be a full, clear, and exact descriptIon of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. My Invention relates to a novel process for transforming certain animal waste into an elastic mass similar in its properties to whalebone and hard'rubber, the ob3ect being to provide a relatively cheap and rapid process for the accomplishment of the result above set forth; and it consists in the various steps hereinaftenfully described and claimed.

* My invention relates more particularly to a process forfltreating o'ertain waste roducts of packing-houses, such as the nonatty waste parts-as, for example, sues.

My rocess consists in first eliminating from the waste all fats and fatty substances, such as glue, gelatin, or gelatinous matter. This is most readily accomplished by placing the said waste in a bath consisting approximately of water, by weight, eighty parts; acetate of lime, four parts. Thls cient to treat about one hundred parts of the animal matter, which is allowed to remain imto be close to each other.

mersed therein for a eriod of forty-eight hours, more or less. en removed from the said bath, he waste is practically white and entirely free from fat, glue, or gelatin;

The said waste is then placed in a second bath consisting approximately of Water, by weight,

eighty parts; chlorid of strontium, two parts. Inthis the material is immersed, the second bath being also rendered acid by the chlorid of strontium. To this bath is added, after the chlorid of strontium is fully dissolved, about one part, by weight, more or less, of sulfate of iron. The sulfate of iron has the effect of shrinking the waste, so as to cause the fibers After remaining in th last-named bath for forty-eight hours, more orless, the strips of materia are stretched upon boards either isolated from each other or in contactand are compressed thereon by I Specification of Letters Patent.

' hydraulic pressure of four hundred pounds to the square inch, more or less, and are allowed to dry in the presence of the pressure thus maintained. Those strips-which are in contact with each other are caused to cement themselves together underthe actionof the applied pressure so ifirmly as to produce a substantially homogeneous mass either in strips, sheets, or blocks. trimmed as desired.

The finished products are normally of about the color of rosin, but may be dyed to any desired color by introducing anihn dyes in the chlorid-of-strontium bath;

The finished product is extremely hard, tough, and elastic and affords an excellent and relatively cheap substitute for whalebone, hard rubber,-and similar materials. The resulting. roduct is capable of beinglreadily polishe and is'genera ly of great uti 'ty.

"I claim as my invention 1. The herei -described process of treating These are afterward hoursmore or less, then stretching said Waste over boards and drying the same In the presence of mechanical -applied high ressure. 2. The herein-described process 6 treating animalwvaste which consists primarilyin sub-' 3 iecting said waste to the action of an'aciduou's calcic bath to eliminate the fatt oonstit uents, then subjecting said defatte wasteto the action of dilute chlorid of strontium and iron sulfate, then stretching the same, and drying the same under compression.

" 3. The herein-described process of treating animal waste which consists in first subjecting said waste for a period of forty-eight hours,

more or less to the action of a dilute acidulous calcic bath, then subjecting the same for'a similar period to the action of dilute'chlorid of strontium and sulfate of iron, and subsequent] y drying and compressing the same.

4. The hereIn-described process of treating animal Waste which-consists in first immersin one hundred parts by weight thereof in a solution consistin approximately of eighty parts by weight of water and four parts ace- 'tat'e of lime, for a period of forty-eight hours I In testimony whereof I have signed my m re or less, then subjecting said Waste for a name in presence of two subscribing Wit- :0 Pfiliod of fofftyeight holurs H101; 011'1 lless1 t? nesses.
